The pop star announced her partnership with Hasbro on Feb. 2 on her official website.

“Dancing has been such an important part of my life since I was a little girl,” Spears said in a press release. “As soon as I saw the new Twister Dance game, I knew I wanted to be involved. I think kids will love rocking the spots and dancing to the music as much as my boys and I do. It’s a lot of fun!”
